Domain for lots with positive quantity

the problem is that we can't filter depending on non stored fields and we can't store computed fields and the quantity field is computed and non stored.

So I solved it this way, Finally:
in the model:

_inherit = 'stock.production.lot'

available_to_choose = fields.Boolean('Available', store=True, compute='_available')

@api.depends('quant_ids', 'quant_ids.reserved_quantity', 'quant_ids.quantity', 'product_qty')
def _available(self):
    for lot in self:
        if lot.product_qty <= 0:
            lot.available_to_choose = False
        elif lot.product_qty > 0:
            quants = lot.quant_ids.filtered(lambda q: q.location_id.usage in ['internal', 'transit'])
            for q in quants:
                if q.quantity - q.reserved_quantity > 0:
                    lot.available_to_choose = True
                elif q.quantity - q.reserved_quantity < 0:
                    lot.available_to_choose = False

@api.onchange('product_qty')
def _onchange_usage(self):
    if self.product_qty > 0:
        self.available_to_choose = True
    else:
        self.available_to_choose = False

in the view:

     domain="[('product_id', '=', product_id), ('available_to_choose','>', 0)]"/>

Abdelhalim KADDOUR GUETTAOUI

domain="[('product_id', '=', product_id), ('available_to_choose','>', 0)]"/>
available_to_choose : is boolean fields
i think you want to say that
domain="[('product_id', '=', product_id), ('available_to_choose','!=', False)]"/>

Hi Mr.Ali,

In odoo 13 inventory_quantity field is defined and used in stock.quant model for viewing the current inventory of the products in specific location.

You have used that field in domain for lot which is stock_production_lot and i dont know why you didn't get an error for specifying in view.

Correct me please if am wrong.

Thanks

yeah, I discovered that and changed the code but still it's not working:

<record id="view_stock_move_line_operation_tree" model="ir.ui.view">
<field name="name">stock.move.line.operations.tree - stock_picking_filter_lot</field>
<field name="model">stock.move.line</field>
<field name="inherit_id" ref="stock.view_stock_move_line_operation_tree" />
<field name="arch" type="xml">
<xpath expr="//tree/field[@name='lot_id']" position="replace">
<field name="lot_id" groups="stock.group_production_lot"
attrs="{'readonly': ['&', ('package_level_id', '!=', False), ('parent.picking_type_entire_packs', '=', True)]}"
invisible="not context.get('show_lots_m2o')"
domain="['&', ('product_id', '=', parent.product_id), ('company_id', '=', company_id), ('product_qty','>', .0)]"
context="{
'active_picking_id': picking_id,
'default_company_id': parent.company_id,
'default_product_id': parent.product_id,
}"
/>
</xpath>
</field>
